Abstract: Systems and methods for managing virtual collaboration systems are disclosed herein. A virtual collaboration system includes a distributor communicatively coupled to a first network and a second network having different network characteristics from the first network, the distributor configured to receive first media streams from at least one first network node, and to transmit the first media streams to at least one second network node; and a management subsystem adapted to dynamically configure a topology of a virtual collaborative event, wherein configuration of the topology includes a determination of media stream connections among the distributor and the at least one first network node based, at least in part, on at least one policy, and wherein the media stream connections establish and maintain virtual relationships among the at least one first network node and the at least one second network node.

Abstract: A method of creating a synthetic bridge (100) has select data (406) logically extracted from an application layer of a first network (12A) which contains one or more first data streams to be transported to a second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B). Select data (406) is logically extracted from an application layer of the second network (12B) which contains one or more second data streams to be transported to the first network (12A). The two or more first and second data streams are transported over separate sets of non-network media link interfaces (130-133) that only allow for limited information encoding and inherently prevent any network protocol information from being passed with the two or more first and second data streams until after the two or more first and second data streams are in the control of the opposite network from which they were transported.

Abstract: A system including a first node configured to receive first data in a first format that specifies a network destination for the first data and convert the first data to second data in a second format that does not specify a network destination for the second data and a second node configured to receive the second data from the first node over a first connection and convert the second data to third data in a third format that specifies a network destination for the third data is provided.

Further, the management subsystem is configured to dynamically manage the topology of a virtual collaborative event based on the node signals.

Abstract: Systems, methodologies, and media associated with videoconferencing are described. One example system includes video display devices and audio output devices to output video and related audio received from a remote videoconferencing location(s). The example system includes a distribution logic to selectively route audio data to an audio output device(s) and to selectively route video data to a video display device(s). The routing may be based, at least in part, on a relationship between an audio source and a video source. The result of the routing is to cause audio outputs to be acoustically associated with related video outputs so that different audio and video outputs will be spatially distinguishable and so that audio is attributable to related video.

Abstract: A video conference system includes a first video conference environment, and a second video conference environment linked to the first video conference environment. Each video conference environment has a conference view direction and a reference view direction, the reference view directions being symmetrically oriented with respect to the conference view directions.

Abstract: A coordinated media control system includes a node manager, a device control system, and a device. The node manager is operatively connected to a first node. The device control system is operatively connected to the node manager. The device is operatively connected to the device control system. The node manager is configured to establish and coordinate media streams for transmitting media from the device to a second node or for receiving media to the device from the second node.

Abstract: A technique for enhancing the illusion of physical presence in a common space during a multipoint video conference is disclosed. The technique may include controlling the appearance of a first portion of the video images separately from an appearance of a second portion of the video images to achieve a consistent image appearance across the multipoint videoconference.

Abstract: Systems, methods, media, and other embodiments associated with video encoder adjustment based on latency are described. One exemplary controller embodiment includes a latency determination logic to determine latency between a first video conference node and a second video conference node, and, an encoder adjustment logic to adjust latency of a video encoder based, at least in part, upon the determined latency.

Abstract: A method of videoconferencing includes arranging a portable environment to include a first wall generally parallel to and spaced from a second wall and facing a videocamera on the first wall toward the second wall. An on-camera subject zone is implemented between the first wall and the second wall via: (1) setting a field-of-view of the videocamera to include the second wall while excluding a peripheral edge of the second wall; and (2) positioning a subject station between the first wall and the second wall and setting the on-camera subject zone within a boundary defined by the field-of-view of the videocamera extending from the subject station to the second wall.

Abstract: Cameras are adjusted by setting magnifications of two or more cameras to be substantially equal, focusing the two or more cameras, and setting the two or more cameras so that portions of an object captured thereby when displayed are aligned.

Abstract: A video conferencing system includes a camera and a display within a room. The camera is directed towards participants in a foreground against a background. The room has lighting defining at least foreground luminance. The display defines maximum display luminance, and the display and flare of the room define minimum display luminance. The camera, the display, and/or the room are adapted to provide one or more of the following. First, that the maximum display luminance is greater than the foreground luminance but less than the foreground luminance times a first constant. Second, that the maximum display luminance is greater than the minimum display luminance by more than a second constant. Third, that illumination color of foreground images displayed on the display substantially match illumination color of the foreground. Fourth, that a color of background images displayed on the display substantially matches a color of the background.

Abstract: A method is described for aligning video streams and positioning camera in a collaboration event to create a blended space. A local physical environment of one set of attendees is combined with respective apparent spaces of other sets of attendees that are transmitted from two or more remote environments. A geometrically consistent shared space is created that maintains natural collaboration cues of eye contact and directional awareness. The remote environments in the local physical environment are represented in a fashion that is geometrically consistent with the local physical environment. The local physical environment extends naturally and consistently with the way the remote environments may be similarly extended with their own blended spaces. Therefore, an apparent shared space that is sufficiently similar for all sets of attendees is presented in both the local and remote physical environments.
